GRINDING, POLISHING, OR BUFFlNG MACHINE.

SPECIFICATION forming part of Letters Patent No. 648,499, dated May 1, 1900. Application filed August 28, 1899. $erial No. 728,673. (No model.)

To aZZ whom it may concern:

Be it known that I, JosnPH KOENIG, a citizen of the United States, and a resident of Two Rivers, in the county of Manitowoc and State of Wisconsin, have invented certain new and useful Improvements in Grinding, Polishing, or Buffing Machines; and I do hereby declare that the following is a full, clear, and exact description thereof.

My invention has for its object to provide simple economical machines for grinding, polishing, and buffing fiat articles, especially metal toilet-comb blanks; and it consists in certain peculiarities of construction and combination of parts hereinafter particularly set forth with reference to the accompanying drawings and subsequentlyclaimed.

Figure 1 of the drawings represents a plan view of a grinding, polishing, or buffing machine constructed according to my invention,

partly in horizontal section; Fig. 2, a vertical transverse section of the same indicated by line 2 2 in Fig. 1, certain of the parts being broken; Fig. 3, an elevation illustrating parts of the machine in vertical longitudinal section, the plane of the view being indicated by line 3 3 in Fig. 1; and Fig. 4, a detail vertical transverse section of a portion of the machine, the plane of this view being indicated by line 4: 4 in Fig. 1.

Referring by letter to the drawings, A indicates the horizontal base of my improved machine, provided with front standards 13 and rear standards C at intervals of its length. A longitudinally-grooved hollow shaftD turns in a pair of the front standards, and another shaft E turns in the rear standards.

Fast on shaft D is a drum F, and projecting from one edge of the drum at regularin tending outer flanges, and set-screws e are engaged with these flanges and the rim of the drum.

A wheel H is in spline connection with the longitudinallygrooved portion of shaft D, and a stay-hook f, fast on one of the standards B, engages an annular groove in the hub of said wheel, the latter being provided at regular intervals of its periphery with notches that correspond in number to the work-clamp ing mechanism in connection with the aforesaid drum.

Arranged'to turn in a pair of the standards B is a shaft I, provided with a driving-pulley J and a one-toothed wheel K, the latter being arranged to have its tooth act in the notches of the wheel H, whereby the latter turns the distance of one notch in every revolution of the latter shaft, the number of notches being equal to the number of work-spaces on the periphery of the drum F aforesaid. A camwheelL is fast on shaft 1, and a yoke M, in pivotal connection with lugs g on the machine-base, has a lug h engaging the camwheel.

The upper ends of the yoke M are forked and engaged by lateral arms e' of a partlypolygonal bar N, that is turned around at one end and fitted in a screw-threaded sleeve j, held loose thereon by any suitable means, this sleeve being engaged with a tapped end of the shaft D, as clearly shown in Fig. 4. The partly-polygonal bar N is guided in one of the standards B and reciprocated incidental to rotation of the cam-wheel L, the latter being timed, as shown in Fig. 1, to insure of said bar being at rest when the toothed wheel K is operating to turn the notched wheel H the distance of one notch.

From the foregoing it will be understood that I provide for intermittent reciprocating and intermittent rotary movement of the drum F and the material clamped thereon.

The pulley J is driven by a belt trained on another pulley P, rigid with shaft E, the latter being provided with a main driving-pulley Q. (Shown in Fig. 1.)

Loose on shaft E are vertically-disposed arms R, connected by an upper offset augular bracket S, and arranged to turn in the upper ends of said arms is a counter-shaft T, provided with a pulley U in belt connection with a pulley V on shaft E aforesaid. The arms R and bracket S constitute a pivotallyadjustable frame having a depending stop lug 7c in opposition to a set-screw m, that turns in a wing '11 of one of the standards C, and a hand-lever W, extending from said frame, is

connected by a spiral spring p with the machine-base.

ing part of the pivotally-adjustable frame.

Each arm has its free end in the form of a bearing for an arbor Y, to which a grinding, polishing, or buffing wheel Z is made fast,

and a pulley s on each arbor is in belt connection with another pu lleyt on the counter= shaft T aforesaid. The arms X are otdiifen ent lengths, and the several wheels Z are p0- sitioned' to act individually upon as man y different blanks G, held upon the periphery of the drum F above specified, the several Wheels being in operation at the same time.

The pressure of the Wheels is regulated by adjustment of the set-screws r, and the pivotal frame above specified is operated to bring said wheels in and out of contact with the material to be ground, polished, or buded, set-screws on serving to limit movement of said frame in one direction.

the drum F, and as the latter is automaticn ali ytrayeled in either direction longitudinally of the machine the several wheels operate on as many opposing devices clamped on said drum. Owing to intermittent rotary movement of the drum each of the devices clamped thereon is operated upon by each of the severalwheels-in the time required for a complete revolution of said drum.

' The general construction and arrangement of parts herei-n set forth constitute a practical application of my invention; but the mecha'n i'cal details of the machine may be more or,

less varied Without departure from the scope of said invention.

Having thus described my invention, what I claim as new, and desire to secure by'L'etters Patent, is-

1. In a grinding, polishing or buffing machine, a drum having intermittent reciprocative movement and intermittent rotary movement, a grinding, polishing or bufling wheel arranged to operate upon material held on theperiphery of the'drum transversely of the same at regularintervals, and means for driving the wheels.

2. In a grinding, polishing or buffing machine, a drum having intermittent reciprocative movement and intermittent rotary movement a plurality of grinding, polishing or buffing Wheels arranged in successive order to operate upon material held on the periphery of the drum transversely of the same at regularintervals, and means for driving the wheels at the same time from a single shaft.

3. In a grinding, polishing or'buffing machine, a drum having intermittent reciprocative movement and intermittent rotary moveim'ent, a tilt-frame, arms .in pivotally-adjustable connection with the tilt-frame, spindles carried by the arms, means for driving the spindles, and grinding, polishing or buffing wheels arranged in successive order on said spindles to operate upon material held on the periphery of the drum transversely of the same at regularintervals.

' controlled tilt-frame,means forlimiting movement of the tilt-frame in the direction of pull on the part ofthe spring in connection therewith arms in pivotally-a'djustableconnection with said tilt-frame, spindles carried by the arms, means for driving the spindles, and

in successive order to operate upon material .held by the clamps on said drums.

- 5. In a grinding, polishing or butting machine, a drum having intermittent reciprocative movement and intermittent rotary movement, permanent blocks projecting from one edge of the drum at regular intervals of its periphery, other blocks in adjustable connection with the drum opposite those aforesaid, grindin g, polishing or'bufli ng wheels arranged to operate upon material held between each pair of blocks, and means for driving the Wheels. I

6. In a grinding, polishing or bufling machine, a drum havingintermittent reciprocative movement and intermittent rotary movement, permanent blocks projecting from one edge of the drum at regular intervals of its periphery, other blocks in adjustable connection with the drum opposite those aforesaid, stay-lugs radiatin g from the periphery of said drum to abut material held between each pair of the blocks, grinding, polishing or buffing wheels arranged to operate upon said mate- JOSEPH KOENIG.
